javascript - ...scrollTop($(this)...) -

-
i have few div s .class class scroll position defined child of parent, need assign scrolltop() $(this) , $(".class").scrolltop($(this).parent().find('.child').scrolltop()); but code doesn't work... $(".class").scrolltop( function(){ $(this).parent().find('.child').scrolltop() } ); doesn't work either. clue? this assuming reading question right. have mulitple "class" elements have own "child" elements. need use each set every element separately. $(".class").each( function(){ var elem = $(this); var childsscrollposition = elem.parent().find('.child').scrolltop(); elem.scrolltop(childsscrollposition); } );

How do you send POST parameters to a function in PHP using Fat-Free-Framework? -

-
the documentation on website bit lacking ( http://fatfreeframework.com/routing-engine ). want use shorthand expression of post: $f3->route('post /login','auth::login'); how send params auth->login() function above? this alternative way of writing it, bit longer: $f3->route('post /login', function($f3) { $params = $f3->get('post'); $auth = new auth; $auth->login($params['username'], $params['password']); } ); if mean auth::login should automatically receive post data argument, can't. all f3 route handlers receive following arguments: the framework instance the route tokens (if any) see here example. anyway, if auth->login function you're referring one included in framework , couldn't work in manner since login() function is not route handler . returns true or false . route handler has little bit more that: example, reroute user on success or

python - Understanding matplotlib magnitude_spectrum output -

i'm having problems understanding output generated matplotlib's magnitude_spectrum function call. i have generated sine 50khz frequency, f_s = 488000.0 # hz t = np.arange(0.0, 1.0, 1/f_s) s1 = 100*np.sin(2*np.pi*50000*t) i plot resulting magnitude spectrum, after dividing number of fft bins s1_magspec = plt.magnitude_spectrum(s1,fs=f_s) plt.plot(s1_magspec[0]/len(s1_magspec[0])) the result single spike @ 50khz, magnitude of 50, opposed expected 100. can explain why is? here link ipython notebook describing showing afforementioned code , resulting plot: http://nbviewer.ipython.org/gist/bkinman/22cc15d3ad3b9b2db09e it looks has default setting fft window used. documentation says default hanning window. if use boxcar window instead: s1_magspec = plt.magnitude_spectrum(s1, fs=f_s, window=np.ones(s1.shape)) you'll peak @ 100, straight numpy fft. by way, if edited question put in line of code creating s1_magspec rather relying on notebook vie

javascript - Math formula for positioning a box relative to where the user clicked within constraints? -

this going difficult me explain i'm looking mathematical formula defines position box pops out relative user clicked in column of rows. here's attempt @ articulating mean: https://imgur.com/a/dbja3 the red circle user clicks in column on left , box on right pops out. when user clicks row @ bottom of column box should pop out bottom edge lined bottom of column. if user clicks in middle should aligned middle. box pops out never runs past height of column on left user never has scroll. does make sense? can use css set absolute position of box need formula work out should be. i don't think there's 1 formula satisfy condition, programming can working. start obvious: top := click.y - height / 2 bottom := click.y + height / 2 then refine it: if bottom > container.height -> bottom := container.height top := max(0, bottom - height) elif top < 0 -> top := 0 bottom := min(container.height, height) fi

c - Efficiently compute the modulo of the sum of two numbers -

-
i have 3 n -bit numbers, a , b , , c . cannot calculate (a + b) % c can calculate a % c , b % c . if modulo operation unsigned , know ahead of time a + b not wrap around n bits can instead calculate ((a % c) + (b % c)) % c . however, possible cases modulo operation signed or addition of a , b might lead wrap-around. it looks there might confusion why ((a % c) + (b % c)) % c cannot relied upon work. here unsigned example: unsigned = 0x1u; unsigned b = 0xffffffffu; unsigned c = 0x3u; ((a % c) + (b % c)) % c == 0x1u (a + b) % c == 0x0u here signed example: int = 0x1; int b = 0xe27f9803; int c = 0x3u; ((a % c) + (b % c)) % c == 0x1u (a + b) % c == -2 what want is: ((a+b)%2^n)%c let a+b = k 2^n + d where k = 0 or 1 , d < 2^n . plugging in get: ((k 2^n + d) % 2^n) % c = (d % 2^n) % c = d % c taking previous expression modulo c get (a + b) % c = (k 2^n + d) % c => d % c = % c + b % c - k 2^n % c with n = 32 , in c: unsigned mymod(u

c# - Screenshots of multiple actionbar tabs -

-
i using xamarin , c# suspect problem equally valid in java environment. i have actionbar activity hosts 3 tabs each of hosts fragment. uses viewpager allow user swipe between tabs. the requirement programmatically screenshot each tab , email these attachments. the problem whilst actionbar/viewpager works optimises tabs - isn't creating fragment's view until next in line shown. so, if you're on tab 0 - first tab - fragment view tab 2 null. can't screenshot. to overcome have tried set tab/fragment has null view selected. generates view because setting selected not render on screen view not have width or height value again cannot screenshot (this reason defensive check @ start of code taking screenshot). so, guess question how can force tab rendered on screen correctly filled out , can screenshot? my main code extracts follows: private void emailreport() { list <bitmap> bitmaps = new list<bitmap>(); list <string&

algorithm - Caterpillars and Leaves. Can we do better than O(n*c)? -

-

found question while preparing interviews. suppose caterpillars start bottom , jump next leaf. eat leaf before jumping next. given array represents jump steps made caterpillars. if array [2,4,7], means caterpillar[­0] eat leaf 2,4,6.. caterpillar[­1] eat leaf 4,8,12.. , caterpillar­[2] eat 7,14,21...0 represents ground. calculate number of uneaten leaves. let assume caterpillar jumps next destination if current leaf eaten. means, if caterpillar[7] finds leaf 28 eaten, proceed eat leaf 35. let c number of caterpillars , n number of leaves. the obvious brute force solution iterating on bool array of size n each caterpillar , mark true if eaten or false otherwise. takes o(n*c) time. can better? a caterpillar eats multiple of 'jump step' j , if alone, each caterpillar eat floor(n/j) leaves. now have got figure out leaves have counted several times. example if count leaves dividable 2 first caterpillar, don't have count leaves second caterpillar, jumps 4
